Have you tried coping TOS.txt in Myst Online.app/Contents/Resources/Myst Online.app/Contents/Resources/transgaming/c_drive/Program Files/Uru Live/Cider/URU Live EULA.app/Contents/Resources/, replacing the one in there? There should be a hard link, but it might be broken.

I have no idea what you mean by this. Copying which file .... to where? .... and where's the "hard link" ... sorry ... so confused?

As I understand it, you deleted the TOS.txt file in(1) Myst Online.app/Contents/Resources/Myst Online.app/Contents/Resources/transgaming/c_drive/Program Files/Uru Live

But Cider actually use another one located in(2) Myst Online.app/Contents/Resources/Myst Online.app/Contents/Resources/transgaming/c_drive/Program Files/Uru Live/Cider/URU Live EULA.app/Contents/Resources/

Depending on which Cider wrapper you’re using, the latter could be an actual, obsolete file or a (sort of) alias. Try coping the TOS.txt in (1) into (2).

Another thing to try, if you haven't already, is to reboot at least 2-3 times. I have noticed that after a MOULa update, my Cider wrapper needs a few slaps on the side of the head before it will behave itself again.

I have no idea why rebooting helps, but it has worked for me several times over now in sorting out Cider misbehavior.

Thank you! I was actually just about to edit my post saying that I found out how to do it with 'port' from the command line:

sudo port install mystonline-cider

EDIT: I was having trouble with the game crashing over and over, and it turned out trashing the directory ~/LIbrary/Preferences/Myst Online Preferences/ fixed it. It appears it was bad combinations of graphics settings that did it.

Yeah, this presently seems to be the only way to get URU on El Capitan. I personally don't use Mac Ports -- I use Homebrew. As an alternative, download both that dmg from the link there and the updated URU launcher -- the dmg on it's own won't work because it has the outdated launcher.

Honestly, I had been using Winebottler for so long. I'll check out the newest version of Winery and boblishman's suggestion and get back to you.

Your right. Winery works well. I didn't have to fight the xQuartz bug I was having with previous bottles I had made. Although I do have to say the Cider wrapper provides much better performance on my older Mac.
